Geographically dispersed disaster restart multitenancy systems
The system and methods disclosed herein relate to an improved hardware configuration for geographically dispersed data restart (“GDDR”) systems. Specifically, the teachings herein allow users to reduce the number of operating systems required to run multiple GDDR systems simultaneously by employing multitenancy principles in the system design. The embodiments cover a system for operating multiple GDDR complexes wherein the individual control systems typically required to run each GDDR complex are combined into a single logical partition. We also disclose methods and computer executable products for operating multiple GDDR complexes wherein the individual control systems typically required to run each GDDR complex are combined into a single logical partition.
1. A geographically dispersed disaster restart (“GDDR”) multitenancy system comprising a first GDDR complex and a second GDDR complex, wherein;
the first GDDR complex comprises:
a first primary data storage device and a first secondary data storage device, wherein the first primary storage and the first secondary storage devices are geographically separated from one another; and
a first primary control instance and a first secondary control instance; and
the second GDDR complex comprises:
a second primary data storage device and a second secondary data storage device, wherein the second primary storage and the second secondary storage devices are geographically separated from one another; and
a second primary control instance and a second secondary control instance; the first GDDR complex and the second GDDR complex are run as a single instance of an operating system;
a third GDDR complex communicatively coupled to the first and second GDDR complexes, wherein the third GDDR further comprises:
a first tertiary data storage device; and
a first tertiary control instance, wherein the first tertiary control instance is located on the single logical partition.
